AUTOMOBILE HEATER.

Application led June 10, 1926. Serial No. 115,081.

This application is a continuation in part of my U. S. applicationSerial No. 87,623, filed Feb. 11th, 1926.

The iirvention relates to improvements in l will be highly eiicient anddesirable.

Ordinarily, a casing portion of` the device 'receives air, subject-s it`to the hot exhaust pipe and directs such air upwardly through aregister, but it is a further aim of the invention to make uniqueprovision for permitting direct passage of air through the `above namedcasing portion instead of ,allowing such airv to be trapped therein,when the re 'ster is closed. y Another aim is to make provision wherebytheexhaust manifold and pxipe leading therefrom are utilized for aireating.

With the foregoiiigin view, the inventionresides in the novel subject.matter hereinafter described and claimed, the description beingsupplemented by the accompanying drawings.

Figure 1 is an elevation partly in section, showing the application ofthe invention.-

Figure 2 is a top plan view of a register constructed in accordance withmy inven-' tion.

. Figurey 3 is a vertical longitudinal section on. linev 3-'-3 of Fig. 2showing the heater in condition for operation.

Figure 4: is a duplicate of Fig. 3 with the exception thatit illustratesthe relation of parts when the use of the heater is not desired.

-Figure 5 is a rear end view.

. Figure 6 is al vertical transverse section on line 6-6 of Fig.3.

Figure 7 is a view similar to Fig. 6 but illustrating the manner inwhich the register and the air receiver may-be either assembled orseparated.

'In the drawings above briefly described, MB designates a `portion ofthe ioor boards ofan automobile and P indicates a part of the usualexhaust .pi e, beneath 'said floor boards, said pipe lea ing from theexhaust automobile heaters of the type which heat provide a heater oftheV general type set.

manifold M. The beards B are formed with an opening O above the pipe P,saidv openingreceiving the upper portion of an air receiver 7. In thepreferred form of construction, this air receiver'is formed from asingle sheet metal plate bent upon itself centrally between its ends toprovide it with `a bottom 8 to contact with the lower side of the pipeP, and with a, pair of side walls 9, the upper edges of the latterhaving pro- ]ecting means such as the flanges 10, to lie u pon the floorboards B. Due to the formation of the receiver 7 from sheet metal itpossesses a degree of resiliency suii'icient to permit inward movementofthe side walls i) toward each other. so as to permit upward pas/sageof the flanges or the like 10 through the openinof O. Then, when theside walls are release they move outwardly so that the aforesaidiangesoverlie the floor boards, holding the air receiver againstdownward movement, contact of the bottom 8 with the pipe P 'then servingto hold said receiver.

against any upward shifting.

Means are provided to prevent unintentional inward movement of the sidewalls t)` and in the present disclosure, said means consists. of thewall 11 of a register 12, said wall ittin snugly betweenl the upperportions Of't e side walls 9 and having vappropriate spring arms 13which curve outwardly and pass through openings 14 formed in the sidewalls 9. The arms 13 y prevent accidental upward movement'of the`register 12 from the air vreceiver 7, yet will permit such movementwhenforce is applied, allowing the heater to be quickly and easilyremoved from the machine.

In the present showin the register 12 embodies slots-15 throng escapefrom the receiver 7 the front end of t e` latter being in communicationwith an air-collecting jacket J- around the manifold M, so that vtheairentering the -reoeiver 7, will 'be heated before discharge throughlthe slots 15. A sliding damper pl 16 is shown to' control the -slots 15.

en this damper is open, the rear end of the air receiver-7 is closed bythe means described below, causing` the tra ping and -heating of air insaid receiver.

which air mayV en this damper 16 is closed, as shown in Fig. 4, the

rear end of the receiver 7 is o ened so that air may pass directlytheret roughfrom front to rear. Y

I For closing or opening the rear end `of the receiver 7, in the.manner-set forth above, I prefer-to use a door 17 which is hinged at 18to the rear portion of the register wall l11, so that it may swingto thevertical closed positionof Fig. 3 or may swing outwardly to the openposition of Fig. 4. A link 19 or some other adequate connection, isprovided between the damper 16 andthe door 17 and it will be seen by` a'comparison of Figs. 3 and 4, that when said damper is open, the `door17 is closed. Similarly, as soon as the damper 16 is moved to closedposition, the link 19 automatically opens the door 17 as shown 'in Fig.4. Thus, air may pass uninterruptedly through the receiver 7 withoutbeing trapped and heated therein.

Excellent results may be obtained from the general construction hereindisclosed but it is to be understood that the invention is notrestricted to the precise details selected for Aillustration herein.Various changes may be. made within the scope of the invention asclaimed.

In order to apply the .device it is simply necessary to form an openingin the floor boards Then, the receiver 7 is passed upwardly astride thewpipe P, its side walls'9 are sprung inwardly to permit-passage of theianges 10 through the opening O, and the register 12 is inserted intothe ucplper portion of the air receiver until the hol ing means 13-14become^ engaged. Jacket J is now ap lied and the device is then inreadiness or use. Wheneverthe heater is to be removed from the machine,for instance when it is desired to elevate the floor boards, theregister 12 may be, by the application of suiiicient force to releasethe holding means 13-.14, raised out of engagement with the air receiver7. Then, thel side walls of the latter may be forced inwardly towardeach other ermittin the anges or the like 10 to pass ownward y throughthe opening O, whereupon said air receiver may be rea ily removed. Thedevice is exceptionally simple and inexpensive and particular attentionis directed to the fact that it may be quicklyl and easily applied' andeffectively secured in place without the use of any fasteners such asscrews bolts or rivets. Not

.only is this advantageous when ihstalling the device, but when removingor replacing it for one reason or another.

I claim:

1: An automobile heater comprising an air receiver whose upper portionis adapted forreception in a floor board opening, said receiver havinga, bottom to contact with the lower side of an exhaust pipe, side wallsrising 'from said bottom to straddle the pipe, and projecting means onsaid side walls to lie upon the floor board, said side Walls beinginwardly movable to permit upward passage of said projecting meansthrough the iioor board o ening when the heater is being.

reception in 'a iioor boardv opening, said re-.

ceiver having a bottom to contact with the lower side of an exhaustpipe, side walls rising from said bottom'to straddle the pipe, andprojecting means on said side walls to lie upon the floor board, saidside walls be ing inwardly movable to permit upward pas` sage of saidprojecting means through the floor board opening when the heater isbeing installed, and a register for insertion within the upper portionof the air collector and adapted to contact with said side walls to holdthe latter against accidental inward movement after the heater isinstalled.

4. A structure as specified in claim 3; said register and said sidewalls having inter-engaged means to normally hold the re ister againstupward movement from the air receiver. i

In' testimony whereof I have hereunto aiiixed my signature.
